Ask Max: Back light on G3 PowerBook only stays on after warm-up
I have an older G3 Mac 13™ laptop that I am having issues with the display. If I open my display up too far the lights will go out on it. I then have to close the laptop, and wait for it to go back to sleep, and then open it very slowly to have the lights come on the display. And even then it does not do it all the time. Now once the lights do come on, the display can not be fully opened for a while (What I like to call a warm up) once it is warmed up I can then open it all the way, Is this a Videocard issue or the Ribbon for the display issue?
The G3 and G4 notebook computers have several cables that pass through the hinge mechanism. Repeated opening and closing of the hinge may have worn one of the cables that passes power through to the backlight of the display. Depending on what model of notebook, the cables may be considered as part of the display unit, and should be replaced.
